Patented June 7, 1949 FFICE DIES Paul H. Brinkceter, San Antonio, Tex., assigner to Ed Friedrich, Inc., San Antonio, Tex., a corporation of Texas Application July 19, 1946, Serial No. 684,967

1 Claim. 1

My invention relates to male and female embossing dies and it particularly has for its objects:

1. To provide a die for forming the metal sheets comprising the cooling-coil-plates disclosed in my application for patent Serial No. 684,968 led on even date herewith.

2. To provide an embossing die composed of a plurality of like units of such size as to be interchangeable and such that units may be added or subtracted to provide for plates of different dimensions or sizes.

3. To provide a simple inexpensive set of dies and a simple means to retain the die blocks assembled on the die shoes.

Other objects will in part be obvious and in part will be pointed out hereinafter.

To the attainment of the aforesaid objects and ends invention further resides in the novel details of construction, combinations, and arrangements of parts al1 of which will first be fully described and then be specifically pointed out in the appended claims, reference being had to the accompanying drawings in which:

Fig. 1 is a plan view of an assemblage of male die blocks secured to a die shoe, the marginal fastenings being omitted.

Fig. 2 is an enlarged detail plan view of a portion of the same.

Fig. 3 is a View similar to Fig. 2, showing a portion of the female die.

Fig. 4 is a cross section on the plane of line li-li of Fig. 2 of the male and female dies.

Fig. 5 is a section of the male and female dies on the plane of the line 5 5 of Fig. 2.

Fig. 6 is a detail face view of a portion of a male die, showing a modification.

Fig. 7 is a cross section of the male die on the line 'I-'I of Fig. 6 with a corresponding section of the female die that cooperates with the male die shown.

Fig. 8 is a View similar to Fig. 6 showing a further modiiication.

Fig. 9 is a View similar to Fig. 7 showing the male die in section on the line 9 9 of Fig. 8 and a corresponding section of the female die that cooperates with the male die shown.

Referring now to the'accompanying drawings in which like numerals and letters of reference indicate like parts in all the iigures, 5 and 6 represent the upper and lower die shoes respectively.

The dies comprise a plurality of male and female die blocks, all of which, except those which are used to form the inlet and outlet of the cooling-plate coil of my co-pending application, are

identical in size. Each elongated male die block I has an embossing protuberance 8 having rounded edges, while each female die block I0 has a recess i2 to receive the protuberance 8 of its associated die block l. Each of blocks 1 and I0 is twice as long as it is wide and each has bevelled corners (45) 9 with grooves I I in the same.

The corner blocks I3 have protuberances I4, while the blocks I6 that cooperate with the blocks i3 have recesses I'I. The male block I3 has a bore I5 and the female block I6 has a punch-pin i9 to cooperate with the bore I5. The corner blocks I3 and I6 are square in the embodiment shown in Figs. l to 5.

In the embodiment shown in Figs. 6 and 7 the corner blocks I3@ and IIa are somewhat elongated and the protuberance Illa and recess I 'Ia are so designed as to form an end-opening embossment instead of a face-opening as made by the embodiment of Figs. 1 to 5.

In the embodiment of Figs. 8 and 9 the corner blocks ISb, ith are more elongated than the corner blocks of Figs. 6 and 7. The corner blocks for both the inlet and outlet of the cooling-coil plate to be made with the dies may be the short ones ISF, IIEa or both may be the long ones I3b, IBD, or the short blocks may be used for the inlet and the long blocks for the outlet or vice versa, as may be found most desirable.

The several blocks are secured to their respective die shoes by means of square splines I9 inserted in the grooves I I and secured to the shoes by the bolts 2 I and spring washers 20.

The blocks are positioned on the shoes as indicated in Fig. 1, forming parallel rows of blocks side by side and a single row at one edge in which the blocks lie transversely of the plurality of rows, one block of the single row underlying two blocks in adjacent rows.

With dies measuring, say, 3" X 1% we can make any size plate on 3 variations, either in length or width by just removing or adding additional blocks.

By moving the blocks one-half section from front to back and one-half from end to end, it is possible to make both the front and back sheets of the cooling-coil plate with one set of dies.

From the foregoing description, taken in connection with the accompanying drawings, it is thought that the construction, operation, and advantages of my invention will be clear to those skilled in the art.

What I claim is:

In embossing dies, a pair of die shoes, a set of die blocks for each shoe, one set having protuber- PAUL H. BRINKOETER.
